Nokia will be unveiling its first batch of Windows Phone 8 handsets at tomorrow’s joint event with Microsoft, and some intriguing new details have emerged surrounding the Lumia 920. Wireless charging appears to have joined the mix, and we also have some more details on that PureView camera.

The rumours confirm that the Nokia Lumia 920 will run on a 1.5GHz dual-core CPU backed by 1GB of RAM, as we suspected. The Windows Phone 8 will be pumping out those extra start screen live tiles on a 4.5-inch HD display.

There’ll be a healthy 32GB of storage, though there’s no word here on whether there’ll be a MicroSD port (which Windows Phone 8 supports).

As expected (and previously leaked), the Lumia 920 will look very much like the current Nokia flagship, the Nokia Lumia 900 – hence the similar name, we guess. This means a chunky but pretty unibody polycarbonate design that will come in a choice of eye-catching colours.

Now for the really exciting details. The Nokia Lumia 920 will apparently support wireless charging. This means you’ll be able to simply lay it on a slab-like charging station, and inductive technology built into the handset will accept the charge without plugging anything in.

Don’t worry – there’ll still be a standard charger port, so you’ll still be able to use that car charger you’ve had in your glove box for years.

As we reported previously, the Nokia Lumia 920 will apparently come with PureView camera. As feared, though, closer inspection rather suggests that Nokia is using the positive buzz generated by the Nokia 808 PureView’s extraordinary camera to put another bullet point on the Lumia 920’s box.

Rather than the 41-megapixel image sensor you might be expecting with PureView technlogy, the Lumia 920 will apparently have a more modest 8-megapixel example. Yep, just like the outgoing Lumia 900. The PureView bit seems to be used in relation to some new image stabilisation and camera software. Still, Nokia isn’t known for producing bad camera phones, so let’s see what they can come up with.

We don’t have too long to wait to confirm all these rumours and find out what else Nokia has up its sleeves.
